I2C-BUS PROTOCOL
Addressing and data bytes
For programming the device (write mode) seven data byte registers are available; they are addressable via eight
subaddresses. Automatic subaddress incrementing enables the writing of successive data bytes in one transmission.
During power-on, data byte registers are reset to a default state by use of a Power On Reset (POR) circuit which signal
is derived from the internally generated I2C-bus supply voltage (V5OUT; pin 38). For reading from the device (read mode)
one data byte register is available without subaddressing.

Notes
1. Use of subaddress F0H to F7H (1111 0XXX) instead of 00H to 07H (0000 0XXX) disables the automatic subaddress
incrementing allowing continuous writing to a single data byte register.
2. The state of unused read bits are not reliable; their state may change during development.

Notes
1. X = don’t care.
2. Auto-normal function: if during hi-fi ‘playback’ mode no FM carrier is detected at FMIN (pin 37) the ‘Normal’ mode
audio signal (LININ; pin 21) is automatically selected by the output select function.
a) Hi-fi carrier detection time (i.e. auto-normal release time) can be selected via bit DETH:
‘fast’ mode: 1 to 2 HID periods (33 to 66 ms NTSC, 40 to 80 ms PAL)
‘slow’ mode: 7 to 8 HID periods (233 to 267 ms NTSC, 280 to 320 ms PAL).
b) The status of hi-fi detection can be monitored via the I2C-bus; see bit AUTN of the read byte (see Table 31).
c) If muting is required instead of automatic selection of the ‘Normal’ mode audio signal the normal input level
function should be set to mute; see bits NIL3 to NIL0 of the select byte.

Notes
1. Bit NTSC selects between the system standard settings for NTSC and PAL (SECAM) use. The auto-calibration
function uses the system standard HID frequency of 29.97 Hz for NTSC and 25 Hz for PAL. After calibration bit NTSC
allows immediate switching between the NTSC and PAL system standard.

Notes
1. POR.
2. By selecting STBA = 1 the TDA9615H is switched to low-power ‘active standby’ mode. To reduce power
consumption most circuits are switched off. RFC, line and decoder outputs however remain active. This way the
direct audio selections offered via the line output select and decoder output select functions (bits LOS and DOS of
the output byte) remain operable in this mode. The ‘Output Select’ mode signal is muted.
3. Calibration and I2C-bus registers are not affected by using ‘active standby’ or ‘passive standby’ mode.
4. By selecting STBP = 1 the TDA9615H is switched to minimum power ‘passive standby’ mode. All circuits except
power mute, I2C-bus and the line input reference buffer (voltage at pins 1 to 10 and 44) are switched off for minimum
power consumption. Use of the power mute function (bit MUTE of control byte) ensures pop-free switching of the line
and RFC output to and from ‘passive standby’ mode. To obtain minimum power consumption the power mute
function should be de-activated again during ‘passive standby’ mode.

2. POR.
3. ‘Dub Mix’ is a special selection for linear audio use supporting audio dubbing (a video recorder feature mode for
sound recording of linear audio only). ‘Dub Mix’ connects the AUX input signal to the left channel
(1⁄2AUXL + 1⁄2AUXR) and the hi-fi output signal to the right channel (generally 1⁄2hi-fi left + 1⁄2hi-fi right but also
hi-fi left or hi-fi right can be selected). ‘Dub Mix’ also changes part of the ‘Output Select’ mode settings to ‘Normal’
mode for monitoring of the linear audio recording (see control bits OSN, OSR and OSL of the output byte for
‘Dub Mix’ mode input and output selection).

connection to an external linear audio circuit. The signal selected with the input select function (via
bits IS2, IS1 and IS0) is available in the following ways:
a) Left and right channel combined, optional including hi-fi volume control (1⁄2hi-fi left + 1⁄2hi-fi right).
b) Left channel only (language I), optional including left channel volume control.
Furthermore the SAP input (pin 44), tuner input (pins 1 and 2) or EXT2 input (pins 7 and 8) can be selected
independently. Also a mute setting is available.

Notes
1. When no hi-fi signal is found on tape during ‘playback’ mode the auto-normal function is activated; all output select
function modes except ‘mute’ will be overruled and changed to ‘Normal’ mode. If muting of the hi-fi sound is desired
instead of selecting linear audio the normal input level (bits NIL3 to NIL0 of the select byte) should be set to mute.
Activation of the auto-normal function can be monitored by reading bit AUTN of the read byte.
2. If ‘Dub Mix’ mode is selected via the input select function (see control bits IS2, IS1 and IS0 of the input byte)
functionality of the modes ‘Mix-Left’, ‘Mix-Right’ and ‘Mix-Stereo’ are changed to support audio dubbing input mixing.
Hi-fi channel selection is offered for the input and normal sound is available at the output for monitoring of the linear
audio recording. See also Table 19.

1. Pin 39 (ENVOUT) or bit CALR of the read byte can be monitored to check for successful completion of the calibration.
It is advised to keep CALS logic 1 after calibration to ensure a reliable CALR state.
2. After a change of bit CALS from logic 0 to logic 1, an automatic frequency calibration is performed setting hi-fi
modem, band-pass filter and noise reduction. Use of auto-calibration is only needed after power-up of the supply
voltage (POR).

Notes
1. Bit POR of the read byte can be used to detect the occurrence of a power-on reset situation (bit POR reads logic 1
in case the I2C register contents equal the POR default state). When applying bit POR this way, PORR should be
used after a power-on reset to force a reset of the POR read bit state to logic 0.

Notes
1. Bit CALR = 0 indicates the device is not calibrated. After an automatic calibration is started by setting bit CALS of the
power byte the end of calibration is signalled by this bit. If for some reason a calibration cannot be completed (e.g.
no HID signal available or hi-fi processing is in ‘playback’ mode) CALR remains logic ‘0’. If calibration is lost due to
a power-on reset situation CALR will return to logic 0 as well.
2. Also the envelope output (pin 39) can be used to check for end of calibration.

audio FM signal is detected at FM input
no audio FM signal detected; normal sound is selected instead of hi-fi
Notes
1. When hi-fi processing is in ‘playback’ mode but no hi-fi carrier input signal is detected the auto-normal function is
activated. Auto-normal overrules the ‘Output Select’ mode setting, selecting normal sound (i.e. linear audio) instead
of hi-fi. The state of this auto-normal function can be checked via bit AUTN.
2. The auto-normal function is only active (bit AUTN = logic 1) for hi-fi ‘playback’ mode (bit AFM = 0); during ‘record’ or
‘loop-through’ mode bit AUTN is always logic 0.

DESCRIPTION

0
1
Notes
1. At power-on or during a power voltage dip, an internal power-on reset signal is generated which resets the I2C-bus
data bits to a predefined state. When the internal data bits are found to be in POR state (due to an actual power-on
reset but also if set via the I2C-bus) bit POR signals logic 1.
2. Using the POR bit to detect the occurrence of a power-on reset requires bit PORR to be set logic 1 after power-up.
Setting bit PORR forces the POR bit to logic 0 independent of other I2C-bus bit settings. After calibration is completed
also the CALR bit can be used to detect a power-on reset; calibration will be lost in such situation which is signalled
by CALR = 0.

Notes
1. Signals below maximum input level are handled without internal clipping. Higher input levels however can still be
handled properly by the demodulators. Typical input level equals two carriers of 30 mV (RMS value).
2. Single carrier signal at FMIN of 75 mV (RMS value) and amplitude modulated. Control bandwidth is the modulation
frequency at which the amplitude modulation is attenuated 3 dB by the HF AGC.
3. Sample-and-hold audio distortion is measured using 500 Hz at HID input (pin 40). FMIN: fmod = 10 kHz; ∆f = 50 kHz.
Audio distortion is measured using a 3 kHz 4th order low-pass filter. Value is corrected with 24 dB in order to
calculate equivalent distortion at 30 Hz HID input.
4. Typical value: B = 20 Hz to 20 kHz, unweighted; production testing: B = 300 Hz to 20 kHz, unweighted.

approximately 401.2 kHz. This value effectively reduces
the crosstalk from hi-fi carriers to the video colour signal as
present during ‘playback’ mode using Extended Play (EP)
tape speed.
Automatic calibration; see Fig.7
By means of bit CALS (power byte) the integrated
auto-calibration system is activated. By adjusting the
carrier frequencies, band-pass filters and noise reduction
filters auto-calibration ensures that the hi-fi processing
always is in accordance with the VHS hi-fi system
standard. Calibration is only needed after start-up of the
video recorder; as long as the supply voltage (pin 35) is
available calibration settings remain stable.
NTSC calibration uses the standard 29.97 Hz (i.e.
16.683 ms) HID signal where PAL calibration uses the
standard 25 Hz (i.e. 20 ms) HID signal. The maximum
frequency error after auto-calibration is ±5 kHz assuming
a HID HIGH-time error of maximum 5 µs. To realize NTSC
EP optimization within ±2 kHz, HID jitter should not exceed
1 µs. In general the crystal based HID signal available in
the video recorder can be used without modification.
Auto-calibration is performed with the device in hi-fi
‘loop-through’ mode, no standby or test mode should be
active (auto-calibration demands bit settings AFM = 1,
STBP = 0, STBA = 0 and TEST = 0). After setting bit
CALS (power byte) to logic 1 auto-calibration is started.
Calibration is performed fully automatically, using the HID
input signal as a reference.
After calibration of the oscillators, the band-pass filters are
calibrated together with the integrated ‘weighting’ and
‘FM de-emphasis’ filter of the noise reduction. The total
auto-calibration time needed is 17 HID cycles or less.
End of calibration is signalled by bit CALR of the read byte.
Calibration of the oscillator frequencies is performed by
measuring the number of oscillator cycles within one HID
HIGH period and comparing this with an internal value
stored in ROM. Four different ROM values are available for
NTSC or PAL (SECAM) system calibration of both the left
and right channel carrier.
The envelope output can also be used to monitor
calibration; for this purpose ENVOUT (pin 39) is forced
>2.5 V during calibration. The audio signal to the audio
envelope (level meter) function should be muted;
otherwise the audio envelope output may be >2.5 V as
well making it impossible to detect end of calibration via
the ENVOUT pin.
In case of NTSC calibration a special routine is active for
the right channel carrier calibration resulting in a frequency
difference between the left and right channel carrier of

After a calibration in ‘NTSC’ or ‘PAL’ mode the oscillators
and band-pass filters can be switched between NTSC and
PAL system frequencies without the need for additional
calibration. Switching between these system modes is
executed immediately and can be done in any operational
mode. Frequency accuracy of switching is 100 kHz ±3 kHz
for both carriers. For ‘record’ mode however it is advised
to use re-calibration after system switching; this to obtain
the best possible frequency accuracy. A new
carrier level (e.g. auto-tracking). At the microcontroller only
one A/D converter input is needed for reading of all
necessary information. During ‘playback’ mode I2C-bus
bit EOS offers selection between audio or carrier level
information. Audio level information is always output
during ‘loop-through’ mode and ‘record’ mode however
now EOS offers a fixed selection of hi-fi stereo (i.e.
independent of the ‘Output Select’ mode setting); helpful
when audio level information is used by the microcontroller
for controlling the hi-fi record volume.
auto-calibration can be started by first resetting bit CALS
to logic 0 followed by setting bit CALS to logic 1 again.

dynamic range compression (square root function) are
included for easy read-out. The peak hold function as well
as left and right channel multiplexing is controlled by the
HID input signal (pin 40).
The HF envelope output signal is continuous and derived
from the left channel carrier. HF envelope shows a
logarithmic characteristic.

After the output DC voltage is settled the power mute
function can be deactivated by selecting MUTE = 0.
Now the mute switches are opened showing a high
impedance of 100 kΩ to ground and output current limiting
is deactivated. Note that the time needed for output DC
settling is proportional to the output capacitor value used;
with a 10 µF capacitor a safe mute time to use is 200 ms
(i.e. tmute = C × 20000). Using such controlled muting very
good performance is achieved for power-up, power-down
and ‘passive standby’ mode switching.
Power mute; see Fig.12
Without countermeasures switching of the power supply
voltage (VCC; pin 35) or use of the built-in ‘passive
standby’ mode causes strong disturbances on the output
pins because of the rise or drop of the output’s DC
voltages. The TDA9615H includes three integrated mute
switches to block such disturbances and avoiding the need
of an external mute circuit. By connecting the power mute
switches behind the line and RFC output capacitors
pop-free line and RFC output signals are realized.
At a sudden supply power loss however (e.g. mains power
plug pulled) there may be no time to activate the power
mute function via the I2C-bus. A power-down detector
however instantly activates the power mute function in
case the supply voltage falls below 7 V (auto-mute).
For proper muting supply voltage drop rate should not
exceed 1 V/10 ms.
Power muting is active when control byte bit MUTE = 1.
Because this also is the POR default state, muting is
automatically activated when the power supply voltage is
switched on. The integrated mute switches (MUTEC,
MUTEL and MUTER; pins 13, 14 and 17) are closed,
forming a low impedance path to ground. Furthermore the
line and RFC outputs (RFCOUT, LINEL and LINER;
pins 12, 15 and 16) are current limited to 1 mA to achieve
good attenuation without the need for a series resistor
between output and mute switch. Although the decoder
outputs (DECL and DECR; pins 18 and 19) have no
integrated muting these are current limited also for use
with the integrated mute switches or to assist possible
external muting.

TDA9615H
Do not set MUTE and change STBP at the same time;
to avoid output glitches power muting should precede the
switching of ‘passive standby’ mode. Power muting takes
up approximately 4 mA supply current, so to realize the
minimum power consumption of ‘passive standby’ mode
muting has to be deactivated. Note also the use of ‘passive
standby’ mode to initiate a controlled power-off switching.
The external resistor should have the following
dimensions: value = 39.0 kΩ ±2%; temperature
coefficient = ±50 ppm/K.
Standard hi-fi audio level
Using the application circuit as proposed in Fig.6, the
standard FM deviation of 50 kHz equals a 1 kHz audio
signal of −8 dBV line output level (LOH = 0). A different
standard audio level can be selected by changing the
external filter components of the noise reduction at
pins 24 and 32 (EMPHL and EMPHR); standard audio
level changes proportional to the impedance of the
external de-emphasis filter; see Table 36.
Iref resistor
The external resistor at pin 28 defines internal reference
currents and determines temperature stability of the
circuits adjusted by the auto-calibration function.

The RFC output can be muted by setting of bit RFCM = 1.
When applying this mute the AGC control is reset by
discharging the capacitor at pin 11 (RFCAGC).
INPUT MIX
A new, complete, recording is made on the linear audio
track; afterwards ‘playback’ mode uses linear audio sound
only. This way hi-fi stereo quality is lost but there is total
freedom in defining the new material. Furthermore this
way ‘playback’ mode is no longer restricted to hi-fi video
recorders with output mix option.
Audio dubbing
TDA9615H includes unparalleled functionality supporting
the audio dubbing function of hi-fi video recorders. Audio
dubbing is a feature mode for recording of new sound
material on the linear audio track (i.e. normal sound) of an
existing recording. Audio dubbing can be used in two
different ways.
Selection ‘Dub Mix’ mode of the input select function,
when combined with selection ‘Volume’ mode of the
normal select function, changes the circuit into a mixing
desk. A new linear audio recording can be created mixing
together new and original sound. By use of the left and
right channel volume controls continuous control is offered
over amplitude and ratio mix of the AUX input signal (e.g.
a microphone input) and the original hi-fi ‘playback’ mode
sound.
OUTPUT MIX
A new, partly, recording is made on the linear audio track;
afterwards during ‘playback’ mode the new linear audio
and the original hi-fi sound are combined. This way
hi-fi stereo quality remains and linear audio is only partly
used e.g. for speech only (commentary track). However
there is no control over the original (hi-fi) sound.
This functionality is realized by internal connection of the
AUX input pair to the left channel volume control and by
internal connection of the hi-fi output signal pair to the right
channel volume control. For output and hi-fi selection the
‘Dub Mix’ mode uses, and partly overrules, the output
select function settings. Output select function modes
‘Mix-Left’, ‘Mix-Right’ and ‘Mix-Stereo’ make the normal
sound available at the line outputs for monitoring of the
‘Dub Mix’ mode recording.
‘Playback’ mode mixing of hi-fi and normal sound is
supported by the output select function modes ‘Mix-Left’,
‘Mix-Right’ and ‘Mix-Stereo’ (OSN, OSR and OSL of the
output byte) creating a fixed output signal of
1⁄2hi-fi left + 1⁄2normal.

Note
1. Modes shown in bold are the most used modes.
Output select function mode ‘Mix-Stereo’ is the setting
generally used for audio dubbing. In combination with
setting the normal select function to ‘Volume’ mode user
control over amplitude and ratio is offered for the AUX and
hi-fi signal as follows: (1⁄4AUXL + 1⁄4AUXR) × volume left +
(1⁄4hi-fi left + 1⁄4hi-fi right) × volume right.
Switching hi-fi to a mode other than ‘playback’ or selection
of output select function mode ‘Normal’ should be avoided;
using these settings a signal loop can be closed from
output to input possibly leading to audio oscillation. For the
same reason auto-normal switching is not active during
‘Dub Mix’ mode; in case no hi-fi input signal is detected the
hi-fi sound is muted.

Notes

2. Calibration may be lost when selecting product testing modes.
3. Audio output level for tests 25b and 25c (test output = line out) is typical −6.5 dBV (with input = −8 dBV or FM
deviation = 50 kHz; LOH = 0). Audio input level for tests 25a, 26a and 26c (test input = line in) is typical −6.5 dBV
(for output = −8 dBV or FM deviation = 50 kHz; hi-fi volume = −3 dB). The test outputs and test inputs used for
tests 25 and 26 directly connect to internal signal lines. Signals found here are not compensated for temperature or
tolerance spread, level measurements therefore can be used relative only. Absolute values are no indication of
overall performance.
4. Test 26c (expander test) requires the auto-normal function to be deactivated (i.e. carrier available at FMIN pin).

SOLDERING
Introduction
Wave soldering
Wave soldering is not recommended for QFP packages.
This is because of the likelihood of solder bridging due to
closely-spaced leads and the possibility of incomplete
solder penetration in multi-lead devices.
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
If wave soldering cannot be avoided, the following
conditions must be observed:
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave)
soldering technique should be used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
• The footprint must be at an angle of 45° to the board
direction and must incorporate solder thieves
downstream and at the side corners.
Reflow soldering
Even with these conditions, do not consider wave
soldering the following packages: QFP52 (SOT379-1),
QFP100 (SOT317-1), QFP100 (SOT317-2),
Reflow soldering techniques are suitable for all QFP
packages.
QFP100 (SOT382-1) or QFP160 (SOT322-1).
The choice of heating method may be influenced by larger
plastic QFP packages (44 leads, or more). If infrared or
vapour phase heating is used and the large packages are
not absolutely dry (less than 0.1% moisture content by
weight), vaporization of the small amount of moisture in
them can cause cracking of the plastic body. For more
information, refer to the Drypack chapter in our “Quality
Reference Handbook” (order code 9397 750 00192).
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
6 seconds. Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
Repairing soldered joints
Fix the component by first soldering two diagonally-
opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
